A ward's catheter-associated urinary tract infection rate falls after a catheter-removal protocol is introduced. Before concluding that the protocol caused the improvement, what should the quality team do?
Correct answer: A. Check that the same case definition and data collection method were used throughout
- A. Check that the same case definition and data collection method were used throughout
- B. Assume the decrease was caused by the protocol because it followed implementation
- C. Exclude patients with complex conditions from the second measurement period
- D. Replace the infection rate with staff opinions about the new protocol
Explanation
A fair comparison requires consistent definitions, data collection, and measurement periods. A fall in the rate may also result from changes in case mix or reporting, so timing alone does not prove causation.
